Description
| - BACKGROUND: The quality of berries and red wines is influenced by the cultivar. The aim of this study was to determine the effect of a polyamine biosynthesis (PA) inhibitor on some red grapevine cultivars with a genetically lower quality of grapes and wines. O-Phosphoethanolaminewas used as a PA inhibitor because of its positive effect on the quality of some small berries. RESULTS: The PA inhibitor at a foliar dose treatment of 7.0 g/ha significantly increased the peroxidation inhibition of berries (1.16- to 1.56-fold), the color density (from 1.66% to 69.14%) and the sensory quality of the wines with a lower genetically programmed color quality (Andr' e, Saint Laurent and Zweigeltrebe), but not the higher-quality Alibernet variety. The PA inhibitor predominantly decreased the total phenolic and anthocyanin contents (from 37.0% to 27.5%), and it significantly decreased the contents of free polyamines in all varieties -- very dramatically in Saint Laurent grapes (17.16- to 1.58-fold). CONCLUSIONS: Foliar treatment of red grapevine varieties of a low quality, using O-phosphoethanolamine, can help produce higher-quality wines.
